 many-flowered, scaly-bracteate : leaves orbicular or broadly oval, 1-3 inches

 lobes lanceolate or ovate-lanceolate, lax or with spreading tips, usually 

 half as long as the white or flesh-colored obtuse petals : stamens declined ; 

 anthe.rs with long cells, contracted into a very short neck under the open-

 spicuous: calyx-lobes acuminate-lanceolate, more than half as long as 

 the red petals : stamens declined ; anthers with long cells contracted under ■ 

 the openings into a short neck : style declined, exserted. In wet places 

 in the mountains, California to Brit. Columbia. 



P. picta Smith Rees Cycl. xxix. Scapes 6-12 inches high, 7-16-flow--
